CHECK.

Specification of Letters Patent.

Patented July 28,1908.

Application fi led March 26,1906. Serial No. 308,108.

To all whom it may concern:

Be it known that I, EMMoR KIMBER, a citizen of the United States, residing at Dorchester, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Checks; and I do hereby declare the following to be a full, clear, and exact description of. the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in checks, and the object of my invention is to provide a check which shall be secure against alteration, and in which the total amount of the check will be shown by the water marks in the aper itself.

In t e accompanying drawings; Figure 1 is a view of the face of the check, and Fig. 2 is a face view of a sheet of stamps or coupons ada ted to be attached thereto.

T e check is made of tinted paper, of such a character that the action of alkalies thereon will destroy the tint, and the rinting on the face of the check is done with ink sensitive to acids. The usual way of altering a check is to take out the inkmarks by means of an acid or an alkali, to then restore the paper to its original condition by the use of an alkali or an acid, and then write in the desired amount. This cannot be done with a check made according to my invention without detection, because the tint of the check is sensitive to an alkali, and the ink thereon sensitive to an acid. After the ink has been taken out by an acid the application of an alkali to get rid of the effects of the acid and restore the paper to its original condition will destroy the tint of the paper, thus rendering detection easy.

Of course, the materials used ma be reversed and the check may be tinte with a substance sensitive to an acid, and the printing done with an ink sensitive to an alkali.

Referring to the drawings, the check is in the main of the ordinary type, bearing at the top a blank number and date and the place of issuance and in the center the name of the bank on which the check is drawn, together with an order for the payment of money and the amount of money.

On the left thecheck has an extension separated therefromby a line a leaving a space I), on the u per part of which space is printed the wor s Attach here fractional c for the signature.

checks 10 cents or over, and near the bottom of the space I) are the words Attach here fractional checks under 10 cents.

The check is provided with a blank space The check is also Water marked as follows. Preferably arranged near the top of the check is a water mark (1 giving thena-me of the bank by which the check is made, and on the body of the check is a water mark, such as e, giving the amount in dollars for which the check is made. The paper on which the checks are printed, is made, of course, in long strips, and the water marks are of such a size and laced in such a osition that each check wil contain a com ete water mark showing the number of dollars for which the check is made.

In Fig. 2 is shown a sheet of stamps or coupons f separated from each other by a series of perforations g, so that they may be readily detached from each other. This sheet is provided with means for attachingthecoupons to the main check, preferably by means of an adhesive substance placed upon the back of the sheet of coupons, but any desired method and means of attaching the cou ons to the'check proper may be used.

ach of the cou ons or stamps has printed upon it its va ue, as shown at h,.these values running from 10 cents to 90 cents, and from 1 cent to 9 cents.. Furthermore, each of the stamps has a water mark upon it, such as 11,.giving the exact value of the stamp or coupon. These sheets of coupons are made of tinted paper sensitive to the ac tion of an alkali or an acid, and the printing thereon is done with ink sensitive to an acid tion with the check proper.

It results from'the construction describedthat a check will be roduced which cannot be altered without etection, and in which the entire amount of the check, both in dollars and cents will be shown in two ways; first by the rinting or writing thereon, and second by t e-water marks on the paper.

Unlike the ordinary check, these checksare made in fixed amounts, one dollar, two dollars, five dollars, ten dollars, twenty dollars, and so on,'and if it isdesired to increase the amount of the check for convenience in business, this is done by using the coupons and attaching them to the main check.

.Having thus described my invention,

Letters Patent 1s acid and the other to an alkali,

' exact sum in 1. A check having Water marks thereon indicating a specific sum in dollars, with coupons attached thereto having thereon indications of their face value, said coupons being each water marked so that the entire amount of the check, with coupons attached, in dollars and cents, will be shown by the water marks on the checks and coupons, said check having a tinted body and having printing thereon, the one being sensitive to an substantially as described.

9. A check having water marked thereon the name of the bank on which it is drawn, and having also water markedthereon the dollars for which the check is made, combined with coupons each having water marked thereon a specific value, and having means for attachlng them to the "check proper, said check having a tinted body and having printing thereon, the one being sensitive to an acid and the other to an alkali, substantially as described.

3. A check composed of tinted paper sensitive to an alkali and having water marked thereon the name of the bank on which it is drawn, and also having a water mark thereon designating the exact amount in dollars of the check, said check having writing or printing thereon made with an ink sensitive to acids, and a series of coupons each having a specific face value, and having means for attaching them to the check proper, each of said coupons bearing thereon a water mark denoting its value in cents, substantially as described.

In testimony whereof, I affix my signature, in presence of two Witnesses.

EMMOR KIMBER.
